Panagpawala na Sodium Hydrosulfide panamegley na Sodium Ethoxide tan H2S
Panagparaan panamegley na Sodium Ethoxide tan Dry Hydrogen Sulfide
Pangiparaan na Kagawaan:
Say 150 mL ya flask ya walay sidearm to et kargaan na 20 mL na balon distilado Anhydrous Ethanol insan 2 g na malinis iran piraso na metal ya sodium (anggapoy oxide layers).
Say flask et walay reflux condenser tan drying tube, tan say sidearm et temporaryon akasara.
Kayari na inggapo na pakaporma na sodium ethoxide, walay kaaruman ya 40 mL na anhydrous ethanol et iyarum ed pigaran porsyon anggad sigpot ya natunaw.
Reaksyon ed Dry H2S:
Sakey a tubo a salming so isuksok panamegley na sidearm ed solusyon, tan say amagan H2S gas so ibulos (seguroen ya ag-onloob so dagem pian ag-onloob so dagem).
Say solusyon et napno na H2S, insan salatan pian naekal so antokaman ya onlelereg.
Say filtrate et iyalis ed amagan conical flask, tan 50 mL na absolute ether so inyarum, ya tampol ya mamawala na amputin NaHS.
Say kaaruman ya ether (~110 mL ya amin) et iyarum ed saray porsyon anggad anggapo lay onuran.
Say precipitate et maples ya nasala, urasan na 2-3 beses na absolute ether, tan pamaraan ed silong na vacuum.
Say produkto et walaan na analytical purity. Parad mas atagey a kalinisan, nayarin gawaen so recrystallization manlapud ethanol/ether.
